Link entry in the editor now works.  The example code at https://www.thatsoftwaredude.com/content/8912/create-a-basic-text-editor-in-javascript was a bit naive because it assumes the URL is already known at the moment the user presses the Link button.  We open a box for URL entry, but when the user clicks into that box the original selection disappears.  So we have to save the selection range in hidden fields so we know where to replace the text.
